"Breathe. Let go. And remind yourself that this very moment is the only one you know you have for sure"

The quote recommends that we should take a deep breath, release all concerns and tension, and concentrate on the present minute. We need to let go of the past, which we can not change or control, and not stress over the future, which is uncertain. The only thing we genuinely have control over is the present minute, so we should make the most of it and reside in the present.
